Letters Patent No. 108,169, dated October 11,187.0; antedatcd October 1, 1870.

IMPRQVEMENT IN APPARATUS FQR EVAPORATING SORGHUM-JUICE, COOKING FEED, Jac.'

The Schedule referred to in these Letters Patent and making part of lthe same. -#4M To all whom it may concern Be it known that I, TfroMAs J. NEWBY, of Richmond, Indiana, have invented an Improved Apparatus for Evaporating Feed, Cooking, 85e.; and I do hereby declare the followiugto be a full description thereof, reference being had to the accompanying drawing, in which- Figure l is a perspective view;

Figure 2, a verticalV section of the bottom of the apparatus; and

Figure 3, a plan View of a section of the bottom at the rear of the apparatus.

The same letters in the different-figures refer to corresponding parts.

My invention relates to an apparatusl designed to be applicable to the purposes of evaporating saccharine liquids and cooking feed, and also to culinary and laundry purposes, in which the advantages of cheapness in construction, economy in fuel, and convenience are obtained. 1

To enable others skilled in the artJ to make and use my invention, I will proceed to describe the same with reference to the drawing.

The body of the apparatus is composed of the wooden structure A, which consists of four sides, built upon corner posts G, and a cover having a hinged. section, C.

The bottom av of the apparatus is made of galvanized iron, which is corrugated, and extends a short distance below the sides of the wooden structure.

The bottom a is provided with metal sides, forming it into a pan, and is attached to structure A by riveting, or otherwise. securing its sides to the inner surfaces of the wooden sides.

Another' bottom, b, of sheet-iron, is added, which is placed beneath bottom a. with itsisnrface against o'r close to the latter'.

The bottom b is'secured by being turned up at the sides and riveted to bottom a.

The lower bottom covers the whole' space of the bottom of the structure, excepting that occupied by the nre-box. i

The tire-box D is located centrally, with reference to two sides of the structure, its size being such as may be desirable.

By the arrangement of the parts constituting the bottom of the apparatus, as in my invention, the corrugated bottom serves the double purpose of afjiording extra heating-surface, and ot' forming vtireues.

In the accompanying example, -thc lues, as formed by the-. corrugationsv of bottom a, and the application thereto of bottom l), are separated into three divisions; a central division embraced within the width of the ire-box, and a division on each side thereof.

These divisions, in the example referred to, are the result of the contact of bottom b with the lower sur faces of the corrugations of bottom a, by which the product-s of combustion are confined to the central division of ilues, until they pass to the rear and into a channel or passage, E, shown in fig. 3, by which theyare allowed to pass both ways and return to the front through the side divisions.

Boxes S S' attached to the front of bottom b, and communicating with the side divisions of ues, and pipes H H attached to and communicating with said boxes, with the addition of pipe H", into which pipes H H' converge, serve to carry off the products of combustion, and give the necessary draught tothe firechambers.

,In order to secure the greatest economy of heat, the liquid is passed through tubes F F' F" that surroundpipes H H' H, by which it is heated before entering the interiorof the apparatus, thus economizing heat otherwise lost.

B is a reservoir for the supply of liquid, from which the latter `passes into tubes F F F through a short tube, connecting said reservoir with tube F.

'A small tube, J, connects tubes F-F near their lower ends, through which the liquid ows from said tubes F F', and by means of short tube, I, passes into the corrugated bottom.

The latter tube is provided with a stop-cock, to y regulate the ow of liquid to the apparatus.

The How of liquid into and from tubes F F'. F" is such as to keep them filled.

A perforated loose bottom is applied, when rei quired, for the purpose of holding articles to be steamed in the operation of cooking, lines e,l showing its position.

Fire-box' D is arranged to slide into and out of its position beneath the apparatus, by means of anges, which support it on the edges of bottom b, as shown at t r, ng. 2.

For-conveniencer in skimming, when the apparatus is used for evaporating saccharine liquids, it is designed to hinge one of the sides of the structure at or near its bottom, so that it may be let dowir or removed, in ivhich case rubber, or otherpacking will be used around the corners of said hinged side, to keep the apparatus steam-tight when closed. 4

If desirable, the inside of the wooden struct-ure may be'lined with tin, or other sheet metal.

Pans for drying fruit may be applied beneath the apparatusLon each side of the fire-box, the pans having iianges, and provision made for sliding them in and out for convenience.

Having thus fully described my said invention,

What I claim,-and-desire to secure `by Letters Patent, is-

l. The combination of the corrugated plate a, the plate 71, and the fire-box D, when so arranged that ehei'hc-orrugations form fire-ues, substantially as set 2. The combination of the plates u and b, fire-box D, and convergent pipes H H', when said fire-box is located centrally, and aJ division of flues is made, substantially us described-and for the purpose set forth.

:5. The combination of tube or tubes F surrounding the furnace-pipe or pipes, the reservoir B and tube I, substantially as described, and for the purpose set forth.
